Detailed Description

Contains instantiated TcKeyReq signaldata for operation.

The prepare phase is finished by storing the request in a PreparedOperation record.

AttrMappingBuffer DbUtil::PreparedOperation::attrMapping

Attribute Mapping

This datastructure (buffer of AttributeHeader:s) are used to map each execute request to a TCKEYREQ train of signals.

The datastructure contains (AttributeId, Position) pairs, where

AttributeId is id used in database, and
Position is position of attribute value in TCKEYREQ keyinfo part of the train of signals which will be send to TC. Position == 0x3fff means it should *not* be sent in keyinfo part.
